1-1-2 Features of Safety Control Units
 Programming with Variables
Programming with variables eliminates the need to specify memory addresses so that you can cre-
ate user programs that are not dependent on any hardware considerations, such as the model of the
Controller or the system configuration. This allows you to reuse user programming, even for different
Controller models or system configurations.
 Checking Safety Programs and Safety Parameters
You can verify beforehand whether your safety programs (user program for safety controls that runs
on the Safety CPU Unit) and safety parameters (parameters that are used for safety controls) meet
the validity and safety aspects that are outlined below.
• Validity and safety of programs written with function block diagrams (for function blocks with miss-
ing or incorrect connections, etc.)
• Safety issues, such as the incorrect connection of a standard input to a safety input parameter of
a function block
• Validity of the safety task period
These checks help to prevent design regression and help to ensure the reliability of the safety
designs.
 Debugging
You can connect the Sysmac Studio to perform various types of debugging, including monitoring,
changing present values, and forced refreshing.
